[0050] The delivery parameters include, but are not limited to, delivery volume, delivery components such as water-oil ratio, delivery time and other parameters.

[0051] Compared with the prior art, the application head provided in the embodiment of the present application can feed back the data detected by the skin detection unit to the main control board 5 by setting the skin detection element 2, the power element 4 and the main control board 5, and the main control board 5 controls the power element 4 to automatically adjust the liquid delivery amount, delivery time and other parameters, thereby simplifying the user's operation process, improving the uniformity and accuracy of the application, and making the beauty process more personalized and efficient. The setting of the power element 4 ensures the stability and safety of liquid delivery, and through the automatic quantitative control of the product, it can effectively avoid product waste and unnecessary stimulation to the skin, thereby improving the user experience.

[0052] In one embodiment of the present application, see Figure 5 The coating head also includes a bracket 6, which is arranged in the shell 1. The bracket 6 has a first installation cavity 601 to accommodate the power element 4. A first limiting groove 602 is formed at one end of the first installation cavity 601, and one end of the power element 4 is inserted into the first limiting groove 602.

[0053] In this embodiment, by setting a bracket 6 and setting a first installation cavity 601 and a first limiting groove 602 on the bracket 6, an installation space can be provided for the power element 4, and the power element 4 can be fixed, thereby reducing the shaking of the power element 4 during the use of the applicator head and improving the stability and reliability of the applicator head during use.

[0054] Specifically, see Figure 7 A vent 621 and a plurality of convex ribs 622 are provided at the bottom of the first limiting groove 602. The convex rib 622 can strengthen the structure of the bracket 6 on the one hand, and can facilitate the formation of a gap between the power element 4 and the bracket 6 on the other hand, which is beneficial to the heat dissipation and cooling of the power element 4; the setting of the vent 621 can facilitate the passage of the connecting cables of the power element 4, and also facilitate the heat dissipation of the power element 4.

[0055] In one embodiment of the present application, please refer to Figure 4 and Figure 8 The shell 1 includes a main shell 110 and a bottom cover 120. The bottom cover 120 covers one end of the main shell 110 and constitutes a second end. The bottom cover 120 is provided with a liquid inlet 121 and a second limiting groove. The first installation cavity 601 is open facing the bottom cover 120, and the other end of the power element 4 is inserted into the second limiting groove.

[0056] In this embodiment, by providing the main housing 110 and the bottom cover 120, the housing 1 can be closed to ensure the integrity of the internal structure of the applicator head. The liquid inlet 121 on the bottom cover 120 is connected to the pipeline 3, so that the liquid can smoothly enter the pipeline 3 from the liquid inlet 121, and then be pushed to the liquid outlet 133 by the power element 4. The second limiting groove cooperates with the first limiting groove 602 to further fix the power element 4 and ensure its stable position in the housing 1, thereby ensuring the stability and accuracy of the applicator head when working.

[0057] Specifically, see Fig. 9 The bottom cover 120 is provided with a plurality of supporting ribs 122, and the supporting ribs 122 are provided with a step portion 123, and the step portions 123 of the plurality of supporting ribs 122 are enclosed together to form a second limiting groove. By providing a plurality of supporting ribs 122, the structural strength of the bottom cover 120 can be increased, thereby improving the bearing capacity and service life of the bottom cover 120; the second limiting groove formed by the step portions 123 of the plurality of supporting ribs 122 can not only fix the power element 4, but also leave a certain gap between the power element 4 and the bottom cover 120, which is conducive to ventilation and improves the heat dissipation performance of the power element 4, thereby reducing the energy consumption of the power element 4, and improving the service life of the power element 4 and the use time of the applicator head.

[0058] In one embodiment of the present application, please refer to Figure 1 and Figure 5 The housing 1 and the bracket 6 are long in the distribution direction of the first end and the second end; the bracket 6 also has a second installation cavity 603, and the smear head also includes a battery 7, and the battery 7 and the main control board 5 are installed in the second installation cavity 603. The main control board 5, the battery 7 and the power element 4 are distributed along the first direction, and the first direction is perpendicular to the length direction of the bracket 6. Figure 1 As shown, the direction indicated by the arrow in the figure is the first direction.

[0059] In this embodiment, by providing a battery 7, it is possible to provide necessary power support for the application head, so that the application head can work independently without an external power source, thereby improving the convenience of use.

In addition, the use of the wireless module 9 also reduces the physical connection requirements of the application head, reduces the complexity of the device, and makes the product easier to use and maintain. Through wireless technologies such as Bluetooth or NFC, the application head can be easily paired with various smart devices, and users can enjoy a seamless user experience. At the same time, the stability of data transmission is also guaranteed, ensuring the accuracy and reliability of the application process.

[0069] In one embodiment of the present application, please refer to Figure 1 and Fig.11 The coating head includes a bracket 6 located in the shell 1, and the power element 4 and the main control board 5 are fixed to the bracket 6; the wireless module 9 is arranged in the gap between the bracket 6 and the shell 1, and the wireless module 9 is arranged adjacent to the main control board 5.

[0070] In this embodiment, the wireless module 9 is placed in the gap between the bracket 6 and the housing 1, which not only saves the internal space of the applicator head, but also ensures the heat dissipation of the wireless module 9 and prolongs its service life. In addition, due to the compact layout of the wireless module 9, the overall structure of the applicator head is more compact and easy to carry and use.

[0071] In one embodiment of the present application, see Figure 1 The power element 4 can be composed of a water pump 401 and a motor 402 connected to the water pump 401, ensuring that the liquid can be evenly and stably extracted from the liquid bottle 12 and evenly applied to the skin through the application head. The power of the water pump 401 and the speed of the motor 402 can be adjusted according to the instructions of the main control board 5 to adapt to different application needs and skin types.
